[mapView selectAnnotation:annotationPoint animated:YES];

[mapView addAnnotation:annotationPoint];

Answer 1

You need to center the map by use the following code.

mapView.centerCoordinate = annotationPoint.coordinate;

Answer 2

Milan's solution does what you need without animation. If you want to do this with animation, you should use:

    [mapView setCenterCoordinate:location animated:YES];
